Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. Source inspection found a first-party hook setup path that modifies editor configuration and enables authenticated context exchange with Cachly’s API. The npm postinstall only prints the setup command, so the inspected behavior supports a capability warning, not a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 84.0% - **Started:** 2026-10-12T23:07:13.524Z - **Finished:** 2026-10-12T23:08:32.715Z - **Download time:** 1282 ms - **Static scan time:** 1719 ms - **AI review time:** 76189 ms - **Total time:** 79191 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** The explicit setup flow installs Cachly-owned hooks and adds them to editor configuration. Those hooks can exchange authenticated prompt or file context with Cachly’s service during later agent sessions. - **Trigger:** The user invokes the package’s setup or autopilot CLI command and then uses an editor with the installed hooks. - **Impact:** Project or prompt context may be sent to the configured Cachly service as part of its memory feature. - **Evidence paths:** package.json, scripts/postinstall.js, dist/src/index.js, dist/src/ambient-hooks.js, hooks/cachly-ambient-einblendung.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-12T23:08:32.715Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The setup writes hook files and editor settings; the hooks use the configured Cachly API and credentials for recall and learning requests. - **Rationale:** Source inspection found a first-party hook setup path that modifies editor configuration and enables authenticated context exchange with Cachly’s API. The npm postinstall only prints the setup command, so the inspected behavior supports a capability warning, not a block. - **Files touched:** .claude/hooks, .claude/settings.json, hooks/cachly-ambient-einblendung.mjs - **Network endpoints:** https://api.cachly.dev ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The npm postinstall invokes a script that prints a suggested setup command; setup is activated by an explicit CLI command., That setup path installs Cachly hooks and writes or updates editor hook settings., The installed hook sends authenticated prompt or text context for recall and learning to Cachly’s configured service., The default API endpoint is api.cachly.dev. - **Evidence against:** The reviewed setup behavior is package-aligned and user-invoked; the inspected sources do not establish credential theft or an unconsented install-time attack. ## Affected versions and remediation This report applies to @cachly-dev/mcp-server@0.10.190. - Review the evidence and your use of @cachly-dev/mcp-server@0.10.190 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
